Sleepsacks are a type of bondage (BDSM) gear. Sleepsacks are primarily used to confine a person comfortably for an extended period of time. Similar to a conventional sleeping bag, a person climbs into a sleepsack and is usually zipped into it up to their neck. Generally sleepsacks are very tight on the body, adding to the bondage aspect of the experience.
Sleepsack or sleep sack can refer to:
- An infant sleeping bag, a bag-like garment or covering worn by infants for sleeping
- Sleepsack (BDSM), a type of bondage gear
